I'm baffled at the attraction of the Webasto, AquaHot, etc. I've read dozens of posts of problems and maintenance problems with the Diesel fired heaters. Up and beyond the fact they run on Diesel-I don't understand why you all put up with the constant maintenance and failure rates of these heaters? Plus the initial cost and the maintenance cost ($1,400?) Good Luck, TomC

I saw a H-45 yesterday a Aqua/Hot caught fire and burnt it to the ground ignore the maintenance they are like anything else electric or propane they will catch fire but diesel fired heater are high maintenance

Lot of guys make a living at Fmca rallies just for repairs and maintenance on diesel fired units me I don't like the fuel usage,smell or the noise of the things JMO

Tom, it was on the bus when I bought it. Its there so it going to have to be perfect for me to have it. What state do you live in Tom? I live in MT and travel mainly MT, ID, WY where we very easily see temps -20. Of course they go to -40 as well. What would your other suggestions be?

My fuel would gel in ID then no heat how do keep the fuel supply from gelling a those temps ? I never could even get mine to fire after 0 degrees it would just smoke and Aqua/Hot worked on it all the time

One tech came up with the bright idea to pre heat with a electric heater that one did not set good with me lol

A few years back I left Minneapolis for Florida on Christmas day. I was shocked the bus didn't gel up because the tank had been filled the first week of October.

In 2004 I bought a new Ford diesel pickup in December. Ford filled the tank with 20 gallons diesel at the factory and the dealer topped it off. A week after I bought it it was -9F. It started okay, but a mile or home from home just after getting on the freeway it died. I think it gelled up because the factory probably used summer fuel. It was towed to the dealer and it started after sitting in the sun for a few hours. They never did find anything wrong and no further issues,
